. Be it known that l, Bonner J. WILLIAMS, a citizen of thedlnited States, residing at Lef fayette and dhins streets, Norwood, Cincin nati, in the county of Hamilton and State of Ohio, (whose post-ofceaddress is Lafayette and Adams streets.y Norwood, Cincinnati,

' Hamilton county, (lithog have inventedcer tain new and useful improvements 1n Window-Gleaners,` of which the following is a specification.

y Mv invention relates to'improvenients in window-cleaners designed for cleaning the window-panes of locomotive-cabs, pilot-cabs, -or electric-car cabs, and for any window-pane in an vehicle where it is desired' to clean both sides ofthe window-pane from the in- A side.

The objects of in invention are, first, to provide a sim le, c cap, practical windowcleaner; secon toprovidea window-cleaner free from complicated mechanism and accurate in its operation; third, to i'lal'gie a window- ,cleaner possessin these elements of cheapness and practica ility which will operate to remove all atmospheric condensation, snow,

elect, rain, 'or moisture of whateverkind and to do vso perfectly over the portion ofthe pane traversed and to clean both the inner and outer idee simultaneously; fourth, tornake a 'window-cleaner in the construction of which the yopenings and crevicee will not permit the entrance of cinders, dust, and other objectionable matter. 'l attain 'these objects by the.

construction of a window-clea`ner vas illusvwith it a perspective :view or" the window and sash. Fig. 3 shows a vertical section on hne :r w in Fig. 2. Fig. 4 L'showsa sectional view of Fig. 2 on liney y, hereinafter more. fully u described. Fig. is al cross-sectional view of the cross-head on line s e 1n Flg. elevated one side osition hereinafter more fully described.

Li re numerals refer to like parts throughout the several views. f

In Fig. 1, l designates the sash of the win 3 dow-pane 2. Thetwo vertical sash-rails 1 have a lengthwise slotted portion, as indicated by 3.

This slot 3 asses entirely through the vertical sash-rails and permits the movement of f' the cross-head 6, attached to movable blocks at either end thereof, to which blocks are flas-A tened the ends of cross-heads 6. To crossheads are attached suitable strips e of sufcient ,width to cover slot 3' and long enough to cover said slot 3 its entire length when the window-cleaner is recuinbent at the top. 5 5 designates grooves in which strips 4 move downwardly in the act of bringing the cleaner downwardly. Grooves lextend down in a central portion of the vertical sash-rails and serve the purpose not only to guide the crosshead 6 smoothly, but they serve also as coverings for slots 3 to prevent the ingress of dust, dirt, 'and cinders in the otherwise open slots when the cleaner is at the top of the window-pane 2. it will be apparent here that when the cleaner is down there will necessarilyT be two apertures in the'windowsash-one in each vertical sashrail-open; but when the cleaner is raised it carries with it strips 4, the top ends of which are perinanently fastened to cross-head Hence the long protruding covering-strips 4 Athereby close the apertures against ingress of any dust or dirt. it is further apparent that the cleaner is designed to clean theupper threem fifths of the area of the pane and is never drawn over the entire area thereof. 6 6 designate a double cross-head, supplied on the inn er and outer side with any suitable absorbent, as felt or a rubber eraser, which contacts closely with the pane. 77 indicate the position of this eraser, of which there is one to contact each the inside and outside of the pane simultaneously.

8 indicates ahandle-knob which is attached i to a pin inserted on the inside crosshead, and the knob is encircled by clasp 9, which is pref erablv made of spring-steel fastened in the iniddle to topv sash and adaptedto engage pin 8 and to hold the cleaner merely by fitting closelyT around it, but may be easily disene gaged.

'l am' aware that slight modifications inl construction may be made without injury to the utility of my invention. Hence l do not desire to be restricted to this precise construction. I

Having thus' fully described my invention,

` what I claim as new, and desire to secure by IDO
